Performance comparison of fluorinated and chlorinated donor–acceptor copolymers for polymer solar cells

Author affiliations

Abstract

Fluorinated and chlorinated donor–acceptor alternating copolymers, F-PBTQT and Cl-PBTQT, were synthesized and used as donor materials for polymer solar cells. Among them, Cl-PBTQT exhibited much better device performance, and a single-junction efficiency of 8.16% was achieved, indicating that chlorination could be a better strategy than fluorination to develop highly efficient polymer donors.
